Hydrolysis of $PC{l}_3$ involves the reaction with water to form phosphorous acid ($H_{3}P{O}_3$) and hydrochloric acid ($HCl$). The reaction is:

$$PC{l}_3+3H_{2}O\to H_{3}P{O}_3+3HCl$$

$H_{3}P{O}_3$ is a dibasic acid because it has two ionizable hydrogen atoms, while $HCl$ is a monobasic acid. Therefore, the hydrolysis of $PC{l}_3$ yields a monobasic acid ($HCl$) and a dibasic acid ($H_{3}P{O}_3$).
